Default Re: ALSA and GTX 4XX Series

Just want to confirm, that I have sound over hdmi/dp working with ALSA (no pulse yet)
Info:
  1. GTX 460 (Zotac's)
  2. nvidia driver 260.19.06
  3. ubuntu maverick (2.6.35-24-generic)
  4. linux-alsa-driver-modules-2.6.35-24-generic from ubuntu-audio-dev ppa
  5. unmuted S/PDIF devices in alsamixer (by default, only 1st is unmuted)

I don't use any tricks with "probe_mask"

I don't know how to select proper device name, when I know which eld# is used, but I iterated through all available devices
Code:
$ cat /proc/asound/pcm | grep HDMI
01-03: HDMI 0 : HDMI 0 : playback 1
01-07: HDMI 0 : HDMI 0 : playback 1
01-08: HDMI 0 : HDMI 0 : playback 1
01-09: HDMI 0 : HDMI 0 : playback 1
using plughw device:
Code:
$ aplay -Dplughw:1,3 /usr/share/sounds/alsa/Noise.wav
$ aplay -Dplughw:1,7 /usr/share/sounds/alsa/Noise.wav
...
plughw:NVidia:* works well too.

Does anyone know how to force pulse to use specific alsa device?
